Abstract (en)
[origin: WO2013064386A2] A pump device having a vane-type pump (1) has a check valve (15) in a fluid duct (14) which leads from a pressure region (7) to an under-vane region (11, 12). The check valve (15) blocks in the direction of the pressure region (7). It is thus prevented that pressure can escape from the under-vane region (11, 12) into the pressure region (7) during the start-up of the vane-type pump (1).
